Clavulinopsis umbrinella

Clavulinopsis umbrinella is a very interesting species from a mycological perspective, being quite rare and poorly documented in our region. It can share habitat with other species of its genus in grassy or mossy areas of forests or meadows.

Its coloration, ranging from whitish tones when young to pale brown or brownish in adult stages, facilitates rapid separation from its congeners.

Regarding microscopic characters, its subglobose spores, predominantly 4-spored basidia, and clamped hyphae provide reliable criteria for its identification.

The specimens studied in this work were collected in December in the municipality of Amurrio (Álava) in a plantation of Cupressus sempervirens.
